Hi
I'll take a look - although it looks like the problem is possibly with libaio ?
Is libaio usable with -flto ?
ATM libaio is mandatory for building lvm2.
BTW - why do you need to use this option - lvm2 isn't really CPU cycle bounded
- if there is something slow it's typically some design issue - -flto will not
really improve things here...
